12x150 60° conical copper-plated steel nut - A.I. Tech

The A.I. Tech wheel nut with M12 × 1.50 thread is designed for rims with a 60° taper. Its through-hole design allows the stud to pass through the nut.

Made of 11SMnPb37 steel with a copper-plated finish, it is suitable for rally and track use. The copper plating facilitates tightening and loosening, particularly when the mounting is exposed to high temperatures caused by braking during competition. It also helps protect the nut from corrosion.

This nut has an overall height of 25 mm, an outside diameter of 23 mm, and a 19 mm hex drive.
